Title: Improvements in and relating to ironing machines
IPC: D06F71/06
Filed: 1946-05-06
Abstract: 611,591. Ironing presses. BRITISH THOMSON-HOUSTON CO., Ltd. May 6, 1946, No. 13694. Convention date, May 7, 1945. [Class 138(ii)] Relates to an ironing-machine in which a heated shoe 13 is moved to and from a buck 6 by fluid pressure, and comprises a sleeve 3 which is supported beneath a table 1 and divided by a wall 2 into two cylinders 3, 4, a piston 5 in the upper cylinder 3 for supporting the buck 6, and a piston 9 in the lower cylinder 4 connected to a pivoted arm 11 carrying the shoe 13; by the passage of fluid pressure to the cylinders, the shoe 13 is moved first into alignment with the buck and the latter is then brought into engagement with the shoe, movement of the lower piston 9 controlling the fluid supply to the upper cylinder 3. The buck 6 is urged downwardly by a spring 8, and the arm 11 is biased by a spring 14. A check valve 16, which is mounted in an opening in the wall 2, is normally biased to open position by its weight and a spring 18. The inner end of the cylinder 3 is also connected to the cylinder 4 by a by-pass passage 21 so that, when the piston 9 is at the outer end of its stroke, the passage 21 is uncovered. At the head of the cylinder 4 is a passage 22 connected to the discharge side of an electrically-driven gear pump 24, the inlet side of which is connected to a tank 28. The pump is by-passed by a metering pipe 36 for preventing the build-up of excessive pressure by the pump and also by a passage 29 controlled by a normally-open valve 30. To operate the machine, the valve 30 is closed, and the pump discharge then causes the piston 9 to move downwardly and swing the shoe 13 over the buck. When the passage 21 is uncovered by the piston 9, fluid passes therethrough so as to build up sufficient pressure in the cylinder 3 to open the valve 16 and move the buck 6 into engagement with the shoe 13. When the valve 30 is opened, the springs 8, 14 return the buck and head to their starting positions, the fluid from the cylinder 3 escaping through the passage 21, valve 16 and conduit 22. At the end of its stroke, the piston 9 causes the valve 16 to seat. In a modification wherein the valve 16 is normally held on to its seat by a light spring, pressure in the cylinder 4 above the piston keeps the valve closed during the upward movement of the piston 9, so that the shoe would swing away from the buck prior to lowering of the latter. The weight of the buck and force of the spring 8 effect lowering of the buck as soon as sufficient pressure is produced in the cylinder 3 to open the valve.

Title: Improvements in the separation of impurities from vegetable and animal fatty oils
IPC: C11B3/06
Filed: 1931-05-11
Abstract: Mucilaginous, resinous, and albuminous matters are separated from fatty oils by emulsifying the oils with a small proportion of aqueous phosphoric acid at 15-45 DEG  C., heating the emulsion rapidly to 55-120 DEG  C. and filtering, centrifuging, or settling. 0,1-5 per cent of acid of 10-65 per cent strength is suitable. Water or dilute alkali in smaller proportion than the acid may be added to the emulsion to assist separation; substances assisting precipitation, e.g. active carbon, bleaching earth, silica gel, gypsum, zinc dust, or water-soluble salts such as sodium chloride or magnesium sulphate, may be added with the acid or later. Residual acid and impurity may be removed by aqueous alkali, e.g. ammonia, and by an adsorbent, e.g. active carbon, bleaching earth, silica gel.  The treatment of soya-bean, peanut, linseed, cotton seed, and animal oils is referred to.  In an example, 100 lb. of soya bean oil is intimately mixed at 35 DEG  C. with 1 lb. of phosphoric acid S.G. 1,253 for \ba1/2\be hour, and the temperature is raised to 60 DEG  C. in 20 minutes; 0,2 lb. of water is mixed in for 10 minutes, the whole settled for 3 hours, and the separated impurities withdrawn.  0,03 lb. of concentrated ammona diluted with 0,12 lb. of water is stirred in and the temperature raised to 70 DEG  C., and the liquid settled.  The separated oil is washed with water, dried at 90 DEG  C. and 40 mm. pressure, stirred with 0,25 lb. of bleaching earth, and filtered.

In operation and on pressurising say chamber 13, the secondary piston 21 is displaced to the left by piston 19 whilst secondary piston 20 is held stationary by its abutment against a shoulder 30 of liner 14. On connecting chamber 13 to exhaust the constant pressure in chamber 43 acting against the piston 21 returns it and the connected main pistons to the dead centre position. In a modification the actuating rod 57, Fig. 2, connected to the main pistons 54, 55 extends through a slot 58 midway of the cylinder wall and the secondary pistons 64, 65 slide in liners 62, 63 and the sleeves 67, 68 thereof slide within the sleeve connecting the main pistons 54, 55.

Title: Improvements in the chlorination of butine-(2)-diol-(1,4)
Inventor: REICHENEDER FRANZ
IPC: C07C51/29
Filed: 1960-04-22
Abstract: The invention comprises a process for the chlorination of butine-(2)-diol-(1,4) with at least 2 moles of chloride per mole of butinediol, which consists in treating the butinediol with chlorine at 0-150 DEG C. in aqueous solution, thereby forming an acid-reacting solution, or preferably in an aqueous solution of a mineral acid which is not oxidised by chlorine under the reaction conditions such as HCl, H2SO4, HNO3 and H3PO4.  At temperatures above 60 DEG C. the main product is mucochloric acid (OHC.CCl = CCl.COOH), while at lower temperatures, e.g. up to 50 DEG C., the main product is 2,2,3,3 - tetrachlorobutane - diol - (1,4); other products obtained are 2,2,3,3-tetrachlorobutyrolactone and 2,3-dichloromaleic acid. Hydrogen peroxide, benzoyl peroxide, and/or an ammonium, alkali metal or alkaline earth metal salt, or a heavy metal compound may be present; specified heavy metal compounds are the oxides and salts of e.g. Fe, Zn, Hg, Ni, Pb and Bi, such as zinc chloride, mercury chloride, ferrous sulphate, ferric chloride, vanadium pentoxide and nickel acetylacetonate; 0.1-2% by weight of catalyst, with respect to the butinediol may be used.  During the chlorination, the solution may be irradiated with light of wavelength 250-700 mm .  When mineral acids are used, their initial concentration is preferably 2-4% by weight, based on total acid and water, and the mineral acid solution of butinediol is advantageously preheated before reaction with chlorine. Chlorine may be led into the aqueous or acid butinediol solution, or chlorine and butinediol, by itself or in aqueous or acid solution, are simultaneously led into water or aqueous mineral acid. Alternatively, chlorine is introduced into a preheated aqueous mineral acid solution before the addition of butinediol. The reaction product may be separated from the reaction mixture by cooling and crystallisation, and the mixed crystals separated by fractional crystallisation from aqueous solution, e.g. by way of the alkali salts, or by esterification with alkanols having 1-4 carbon atoms, with subsequent fractional distillation. Specification 803,058 is referred to.ALSO:The products obtained by chlorination of butine-(2)-diol-(1,4) with at least two mols. of chlorine (see Group IV (b)) and consisting substantially of mixtures of 2,2,3,3-tetrachlorobutanediol-(1,4) and mucochloric acid (OHC.CCl = CCl.COOH) are stated to be of value as rematocides, insecticides and fly repellents.  The reaction mixture may also contain hydrogen peroxide, benzoyl peroxide, ammonium, alkali metal or alkaline earth metal salts, or heavy metal compounds. Specification 803,058 is referred to.
